If you're still working out which process fits your workload, it helps to talk it through with people who field these questions every day rather than guess from a spec sheet, and the team behind welding equipment supplier in Thirsk deal with exactly this kind of query on the advice line.
Cutting capacity is usually described in terms of clean cut and maximum cut thickness, and the two are worth distinguishing. Clean cut is the thickness a machine handles with a good edge finish and reasonable speed, while maximum cut is the thickest material the machine will get through at all, usually slower and with a rougher edge. Buying with your typical material thickness in mind, rather than the thickest job you might occasionally face, generally gives a better day-to-day result.
Most people buying their first welder get stuck at the same fork in the road: MIG,
Tec Products TIG or MMA. Each process strikes an arc differently and suits a different type of work, so the right choice depends more on what you'll be building than on which machine looks the most impressive on a shelf.
A gas lens sits in place of the standard collet body and uses a fine mesh to straighten the shielding gas flow into a smoother, more laminar stream around the arc. This generally allows a longer stick-out from the cup without turbulence pulling in surrounding air, which is particularly useful when working in tighter joints or awkward positions where the torch needs to sit further back from the work.
Portability and durability matter depending on how the table gets used. A shop building large frames or vehicle chassis needs a solid, well-supported table that won't flex under load, while a mobile fabricator or someone working across multiple sites benefits more from a lighter, foldable design. Material and construction quality affect long-term flatness too, since a table that warps under heat from repeated welding stops being reliable exactly where it matters most.
Getting the air supply, cutting capacity and portability right for your workshop is easier with some guidance up front, and that's the kind of buying question the team at welding tables UK are set up to help with.
